To (1N zo/11.0772r 1' t may concern l'e it known that-I, FRANK E.' Davis, a resident ot La Crosse, in the county of La Crosse and State oi" Wisconsin, have invent ed certain new and useful Improvements in Seeding-"Machines, of which the following is a full, clear, and exact description.

rhc invention relates to seeding-machines.

In the operation ot' seeding-machines and grain-drills, it is frequently necessary to raise and. lower the soil-openers to pass over obstructions or in passing over land on which no planting is to be done. It is desirable in this class of machines that the raising and huivering mechanism be suseeptlble ot quick operation and will readily respond tothe will of the operator so the maclnne 1n passing over the land will at all tunes be in either operative or inoperative position when A2 0 desired. A readily operable lifting rnechanism for the openers is advantageous in avoiding obstructions, passing over land without.planting when such is desired, and frequent necessity of cbacking the machine to repass over the land at times. In this class ol" machines it is also necessary to employ pressure devices for holding the soil or furrow open at dittcrent depths to correspondingly deposit the seed and such presisur'e and locking-devices for securing' the openersare usually associated with the liftmechanism to hold the openers at dit ferent depths as well as in position to hold the openers in inoperative or riding position.` lt is also desirable to provide controlling means 'for seed-delivery devices which require no special attention of the operator and are always operative or inoperative, corresponding to the position of the openers. It :is also desirable in machines of large sizes to arrange the openers in gangs susceptible of independent and conjoint op.- eration.

@ne object of the present invention is to .provide improved mechanism 'for raising and lowering the openers more quickly than may be done by hand or power and which, `tiutherinore, leaves the hands of the operator tree t'or controlling the team and 'for operating the prcssure-devices when desired.

rlinothcr object ot' the invention is to pro vide improved shitting mechanism for the openers which is susceptible of operation by the foot of the operator z'. e. a footdift mechanism,

The invention still further designs to provide a seeding machine in which the opcration of thc seed-delivery devices are footcontrolled in response to the 4toot-operated litting-meehanism for the soil-openers, so

that when the soil-openers are operated by the foot-lifting devices the seeding-mecha nisni will be correspondingly operated.

rlhe invention also designs to provide footoperated lifting mechanism for a machine having a plurality of gangs of openers whereby the gangs can he indrniendently or conjointly operated.

The invention still further designs to provide a pressure-device for the openers which may be locked to hold the openers in the soil und which may he controlled by a loot-lever.

Another object is to provide a foot-oper able liftingmnechanism for the i openers which automatically holds the openers in raised position, so the use of locking mechanism is not necessary to secure the openers in such position when operating in the field.

The invention designs to provide a seeding-machine ot.' improved construction.

The invention consists in the several novel features hereinafter set 'forth and more pail the openers have been raised by the footlof ver and the lock for the pressurelever has been released. llig. 2 is a longitudinal section of the machine, the lifting mechanism being shown in the position assumed when the furrow-openers are working in the soil and the pressurcflever locked to so hold them. Fig. 2 is a detail of the pressurelever, its leelrand the releusing-mechanism axle or shaft 9 whereby the several parts of the machine are supported. -This shaftl is usually connected tothe carrying-wheels by clutches' or pawl and ratchets as well understood in the art, so that the shaft will be rotated only` when the machine is drawn forwardly and so the lshaft will not rotate when the machine'is moved backwardly. A supporting-frame to which] the .draft-bar or tongue is lusually secured comprises endbars l0, 4a front bar 12, usually formed of 'angle-iron, a reartran'sverse bar 173 which is secured to and extends between the end bars- 10,-a central bar 17, and bars 19 secured to the front bar, all of which Aare rigidly connected in suitable manner to forma rigid frame by which the several partsof the ma;

chine are sustained. TheV frame is pivotal'ly supported bythe axle, being. connected' thereto by bearings 11' secured to the end bars, bearings 20 secured to bars.19 and a bearing v18 secured to central framebar 17. The frame vand-bearings may be of any suitable and well known construction. A. seed. box 1 5 extends across the machine and is sustained by brackets (not shown) secured to end-bars' vl0 of the frame, and by straps 21 secured to the frame in any suitable manner.

Inthe lower portion of the seed-box arey arranged a series of seed-delivery devices 22' which may be of any suitable and well known construction, as the particular construction of these devices forms no part of the present invention. These devices are operated by shafts 23' which extend through the seed-valves 22 and are each operatively and independently connected to the wheelaxle by a sprocket Wheel 24 (see Figs. 3 and 5), chain 25 and a sprocket-wheel 26 mounted on the axle and adapted to be drivenA thereby under control of a clutch 27. Sprocket-.wheel 26 is slidably mounted on the axle and is operatively connected thereto by'v clutch 27, the members whereof are secured to the axle and said sprocket-wheel respectively. A spring 28'yieldingly holds the clutch-members normally in connected relation. One of the.seeddelivery shafts 23 operates the seedfdelivery devices for one gang of openers and extends from the center of the machine to thev end thereof and the other -operates the delivery devices fora the other gang and extends from the center of the machine to the other end thereof.A The purpose being to permit the seed-de vices to Ibe operated in gangs corresponding to the soil-opener gangs.

Each of the clutches for driving the seeddelivery devices, is controlled by a shifter 89 which is pivoted as at90'to a lug .secured to frame-bar 13 and has a forked end adapted to shift sprocket-wheel 26 into and out of connection with clutch member 27. The

shifter has a cam-surface 91 arranged to be shifted by one of the rock-shaft arms 38, to swingv the shifter about its pivot 9() and disconnect the clutch members, said arm 38 and shifter- 90 being operated when the furrowi openers are shifted and correspondingly cause the seed-delivery devices to be conjointly controlled with the openers to render said devices operative when theopeners` are operative and inoperative when the/l openers of the corresponding gang are.

A series of soil or furrow-openers are provided and in the construction shown each comprises a disk 30, a seed-boot 31 and a supporting draglbar 32 which is independently pivoted at its upper and front end-as at 33 to the frame. 'f The boots and disk are connected to 'the drag-bars in manner well understood in the art, the disk being usually set at an angle to openthe soil. The open'- ers may be of any suitable construction and are 'arranged in gangs, each gang being capable of operation vindependently of the other. Flexible tubes 32a each suspended from ,one of the seed-delivery devices 22 convey the seed discharged by the seed- 'valvs into the boots. y

The openers are arranged tov be operated.

in gangs each usually extending from the center of the machine to the end thereof. Each drag-bar is movable independently of the others in traveling in the soil or'over lob structions. Each drag-bar is connected to the liftingsmechanism by .a rod 34 pivoted at 35 to the drag-bar andl is slidably held in artrunnion-collar 37. A spring 36 is interposed between said collar and the drag-bar to provide an independently yielding connection fc". each opener. The trunnion-collars vare each pivoted in the free end of an arm 38, secured td a rock-shaft 39. Rockshafts 39 are journaled in bearings 40 and one of said shafts has secured thereto the arms 38 for one gang of openers and the other rocksshaft 39 has secured thereto the arms 38 for the other gang, each shaft extending from the center of the machine to the end of the frame. Thepurpose of employingindependent rock-*shafts for each soil-opener is to permit one of the gangs to be raised or lowered independently of the other when desired. In the field itis frequently desirable to operate one gang only e. g. when there is an obstruction to one or isc ige'me'ee more openers, the lifting' of one gang is all that is necessarr While the other can remaina bolt 92 and to a curved link 92 which is the openers are raised and little, if any,

when the openers are in thesoil.

A foot-liever and connection is provided for each nano whereb thc o )eners thereoi' I5 b l may be raised conjoiiitly. These :foot-op` erablemechanisms each comprise an arm secured to the rock-shaft whereto the openers are connected, a footdever liti and a connector or bar 4:7 which is pivotally connected to said arm and to an arm 46 on the :footlcver. Each foot-levcr is pivotally connected at 48 to an arm 49 which is rigidly secured to and near the inner end of a shaft 511 for controlling the pressure-lever lock and which is mounted in a bearing secured lto `the frame in anyxsuitable manner and in a bracket 77 Arm 49 serves as a movable fnlcrum for the foot-levcr so the latter will control the lifting connection and also operate the locking-device for the pressure-lever-73. The foot-lever and its connection provide a linkage which may beoperated into. dead centerl relation .(see Fig. lb) when the weight of the openers will be applied to hold the connection in posi# tion to automatically retainthe openers in lifted position and without any locking .mechanism and inde endently ot' the pressureslever and its loc c. l i

Each foot-lever controls one gang or' openers and has an angular end liti" for the 'foot of the operator. Both foot-levers are secured so they" are disposed near the center ci the macl'iine, and are arranged so their angular ends canbe conjointly depressed or released by `one foot of the operator for his convenience .when lboth gangs are to be simultaneously operated. A seat t3() for the operator is sustained in position to make it convenient for him to operate either the iriiotz-lever or the pressure-levers7 by supporting-hars til seein-ed at their front ends` to :tramebar 13 and also to hangers 7l which are secured to the seed-box.

connection also provided :for each l' whereby-the openers thereof may loe operated by hand to raise or lower them in event the ,toot-operated connection becomes iixmfierative and to regu-late or vary the pressure on the soil-(metiers according" to the character ot the soil in which the planting boing done, and tri-regulate the depth of planting. Bressuire-levers 73 are adapted te 98 (see Figst and 6) may bel be operated by hand and cach is connected to one of the rock shafts 39 and openergangs by a link 71k which is connected to an arm 75 rigidly secured to roclesllaft. Each pressure-lever is pivotally sustained at 7h )y a bracket; 77 which is rigidly secured to the frame in any suitable manner. c. y., by being bolted to the hangers 7.1,. 'l'he presA sure-*levers are arranged some distance ironi the center of the machine and in convenient `reach of theoperator. These pressurelevers are each adapted to be locked or secured to canse therock-slmlts lor thtI openers to be held so the openers will travel in the soil at dill'erent depthsl and to vary the pressure applied to" the openers by Sl'irings Bti. 'lhese pressurelerer locks are automatically controlled by the foot-lever, 1i. e., when the foot-lever is operated to litt a gang it initially causes the release of the pressure-lever to free the openers and litting-connections, so they can be operated. The pressure lever-lock is automatiiuilly operated by the foot-lever so no otheroperation is necessary to release the connections, thus renderingry the lifting mechanism op-` irable at all times h f operation of the 'foetlever alone and easily controllalile by the operator without the use of his hand.

Each bracket 77 has teeth 7 8 which. serve as a rack for holding the pressure-lever. A latch 79 adapted to engage either ol the teeth 78 to lock the pressure-lcver and the operating connections for the rock-shalt:

in assigned position when desired. Latch Tt) is adapted `to be operated manually in one direction by a ingeolever 80 which is pivotally connected to the pressuVwleicr near the 'free end thereof and is normally springpressed to engage the rack. liever 755j linl: 7l and arm 75 form a connection tor the rock-shaft whereby the openers ot' a gang can be raised or lowered by hand when de sired and provide means 'for positivelyY sccuring` the rock-shaft in positionv to hold the openers in the soil, at diicreut depths. ln practice it is Yfrequently necessary to lock the rock-shaft and operating-connection when planting in hard soil or sod. it other times when working in loose or sott soil` the weight of the openers` is sullicient to cause them to penetrate the `soil the desired extent.

ll'n order to make it possible at all times to lift the gang by foot and particularly when the roclcshafts ltl are locked, a footlever controlled releasing plate Sli is provided lior leach pressuresleveri whereby, when it is desired lo operate the foot-'lever while the pressure-lever is locked, the latter will lirsl: he released to permit the rocleshal'l's and gangs to be (naci-ated by the 'toot-lever. ',lhis releasing'plate is provided with guide slots tfi through which extend bolts Sil to canse the plate to more inwardly or outwardly and llt) outer edge isconcentricallyformed with lever-pivot 7 6 sot-hat the bolt of the latch 79.

will be held out of engagement with the rack 78 to free the pressure-lever so the ootelever and Aits connectionscan be operated to lift the openers. The releasingplate isoperatedby arm 49 on whichvthe footdever 46 is ful-` crumed and which is secured to the controller-shaft 54, which has secured to its outer endV an arm 84, connected'by alink 85 tothe releasing-plate. A 'stop 87 limits'the 'movement of iarm 84 -in one direction (see 'Fig. la) so that the foot-lever fulcrum-48 at the end of arm 49 will remain stationary at times. Arm' 84 and .link 85` are Aarranged to .'"cross the dead center of their connections when the releasingplate is in its outer or operative position anda spring 86 tends to hold the releasingplat-e in either of its alternative positions.

Vhen the foot-lever is operated to shift fulcrumearm 49 and to rock controller-shaft 54, the releasing-plate will be correspondingly operated; Stop 49a is provided on the fulcrum-arm 49 to prevent the foot-lever linkage from passing too far over'the deadcenter when holding the gangs in raised p0- sition. By reason of the locked o`r self retained relation of arm 84 and link 85, there is no tendency of the releasing-plate and its connections to disturb the dead center of Jthe foot-lever linkage including arm 49. The rackis'also provided with a notch 7 8a by which the pressureeleve'r may be'securely locked to lock the openers in lifted or riding?? position when the pressure --lever is. yhacking-bolt to enter` shifted to cause the said notch. u

The operationot the device will be as fol lows: Assuming the parts to be in raised y position, shown'in Fig. 1b, the footlever and itslifting-connection will bein such position that the weight of the openers will be applied to hold said connections in position to hold the openers in raised position. In such position rocloshaft 39, arm 45, link connector 47, foot-lever arm 46, and ulcrum 48 will be disposed so that arm 45 will tend to in Fig. lbthe lock-releasing `'plate will be in position illustrated in Fig.` l, and the pres- Y' sure-lever will not be locked to rackv 77, the

lrelensingplate being held in position to hold:- latch 79 disengaged from said rack.' The position of the connections shown in. Figs. 1* and la is that assumed when the ,openers have been raised by 4the foot-lever 46 as is usually done in the field. When it is desired to lower the openers and to plant grain, the Voperator will place his foot under -the'free end-of footflever 46 and litt it upwardlyto shiftv arm 49u ward'ly during the initial operationof the cot-lever. f As arm49 is raised by said foot-lever, the foot-lever linkage v46', 47, 45, crosses the dead-center so that the weight `of the openers will be applied.

through saidlinkage to swing arm 46. down- A wardly .while fulcrum-arm 49 is swinging upwardly to operate the releasing-plate 81 to release the pressure-lever lock 79 for engagement withxrack-teeth 78. Resultantly ,of vthis initiallift of the foot-lever 46, the members of the footlever linkage will' be disposedso that the openers will be freev toandfwill fall Fig. 2,?, the pressure-lever 7 3 will be locked when latch 79 of the pressurelever reaches v to the ground and the releasing-plate 81, having been operated into positionseen in Ithe highest of the notches 7 8. Resultantly of the initial lifting-movement `of the -ootv.

lever 46 bythe operator to swing the fulorum-arm 49 upwardly, the openers will bev released and fall to the ground and the pressure-lever will be locked in the highest ofjthe may be low red and locked in a lower notch as shown in Fig. 2.V It will be observed that notches 78 of the rack. If greater pressure upon the openers is desired, Ithe ltland-lever; l

when the openers arein the soil (Fig. 2) the 1 footlever linkage is free to allow the rockshaft and pressure-lever to be adjusted for planting at dierent depths.

When 'the rock-shaft for either gang of openersis lowered as a resultof the operation of the foot-lever therefor, the arm 38 v on rock-shaft 39 whichcontrols theclutch for the driving-mechanism for the seed-delivery devices of the corresponding gang,

will ride. along cam-surface 91 to permit the shifter 89 to swing about' its pivot 90 and spring 28 to operatively connect the vclutch,- members and cause them to y'operate the seed-2 delivery devices.

ers and seed-delivery .devices will be simultaneously rendered operative or inoperative. To raise either gang of openers and discontinue planting, it is only necessary to op- Resultantly, the seed-de livery. devices are controlled by the footlever and its lifting connections so the open crate the corresponding foot-lever 46 downwardly, which will causethe openers of a gang to be raised and the seed-delivery mechanism be rendered inoperative. Assuming thel furrow-openers to be in lowered position-seen Vin Fig. 2, the operator will` dei press the :toot-lever which owing to the rockshaft 1,39 being locked will cause fulcrumarm 49 to operate into position seen in Fig. l". Said arm will'during the initial movement of the foot-lever operate rock-shaft 54 to shift the releasing-plate 81 fto release the pressure-lever and its lock. When arm 84 contacts with stop 87 further movement of Leva-ece `the loot-lever in downward direction will canse it to swing about its fulcrnln 48 (which is stopped by engagement of arm 84 with stop 87) until arm elo has been shifted so the toot-lever linkage will pass into dead center relation and be held in position shown -linli`i`g`g'-tA l. lhc 'toot-litt connection willv then beklisposed so the soil-openers Will be automatitarlly held in raised position, and

the releasing-plate will hold the pressureleverlock in iiioperative position (Fig. 1b).

Vhenever it is desired to raise the furrow-openers bymeans ot' the hand-lever 73,

e. g., if the toot-lever connection should be- M, come inoperative, and to lock the openers in raised position as shown in lt`ig. 1 for transportation, this may be done by means of-ahand-lever Assuming the furrowopeners to be lowered and the lifting-connections in position seen in Fig. 2 the operator will nnlook the hand-"lever 73 by means of. finger-lever 80 and raise said lever until' the latch 79 passes into notch 78 ot lthe rack 77. This notch is disposed slightly 25, beyond the point to which the latch passes when the lln'row-openers are raised by the toot-lever` 4G so that `when the furrow-openers are raised by the foot-lever and its linkage, the latelrwill not pass into engagement with notch 7 Sa. To lower the furrow-open ers when they have been locked in raised position as shown in Fig. 'l it is only necessary to release the lever 73 'from the rack so the 'turrow-openers will tall into the ground. 35, Manifest ly, by the operation of the tootlever in one direction, the soil-openers can be quickly and convmriently-litted so they will be automatically held in raised position when they are raised by the foot leve' and a@ by tripping the too-t'dever the openers will be released to cause them to fall and enter the ground. l`he controlling-mechanism for the pressure-lever is timely operated by the 'toot-lever to secure the 't1irrow-opemrs in the soil, and to permit the pressure-lever to be shifted by its operating connection, whilethe 'toot-lever is being operated.

lt it is desired to render both gangs operative or inoperative simultaneously, the operator can conjointly and correspondingly operate both 'toot-levers with one foot. these beingl arranged 'for conjoint aswell as independcnt control. y"t either foot-lever linkage should become broken or disarranged, the openers can still be controlled by the sore-levers.
